The invention relates to the catalytic treatment of a gas oil feed stock, distilling between 150 DEG and 530 DEG C., in a reactor zone whose temperature is comprised between 200 DEG and 500 DEG C., the pressure is comprised between 15 and 80 bars and containing a hydrogen form zeolite as catalyst, in the presence of a quantity of isobutane representing from 5 to 100% of said feed stock. The process is particularly suitable for the improvement of the filtration temperature limit of the gas oils. |
